Abstract: The basic idea of virtual pen is to develop a interface or the connection between the user and computer screen human interaction with the computer is not just bounded to keyboard , there are many other means like gesture,speech, expressions etc. Virtual pen is a system that serves on arduino and machine learning process. This virtual pen is the model where ,user can enter text on the screen by the holding the device in the hand which is a constituent of arduino and accelerometer, Thus making a motion or moving it in specific direction in air is read and displayed on the screen with

Keywords: Arduino, Accelerometer, Button switch, Vector machine algorithm, pyGARL.
